- Hi there, I would just like to ask the Copenhagen interpretation of Light that is both as a particle and a wave and would like to verify if I understand it right. So basically Light exists as both a particle and a wave but we'll only know what state it is in when we test it or we won't know what state it will be unless we open the box (in reference to Schrodingers thought experiment). Because before diving to the quantum mechanics interpretation of light, I thought of it as a particle moving in a wave but since both cannot exist at the same time or at least it would bend our understanding of the two. I would like to receive some enlightenment thank you!arrow_forwardAlbert Einstein is pondering how to write his (soonto-be-famous) equation. He knows that energy E is a function of mass m and the speed of light c, but he doesn't know the functional relationship (E = m2c? E = mc4?). Pretend that Albert knows nothing about dimensional analysis, but since you are taking a fluid mechanics class, you help Albert come up with his equation. Use the step-by-step method of repeating variables to generate a dimensionless relationship between these parameters, showing all of your work. Compare this to Einstein's famous equation—does dimensional analysis give you the correct form of the equation?arrow_forwardQuantum Mechanics: please explain clearly with reasoning/steps Q1) "~P(x,0) = [Ax Ах 04x49/2/2 2 A(a-x) a≤x≤a a) SKETCH + (x₁0) AND EXPLAIN WHY:arrow_forward
- Albert Einstein’s theory of relativity, which he developed in the context of his special theory of relativity, are inconsistent with several experiments. This is not the case with the general theory of relativity, whose predictions coincide with the experiments without contradiction and whose experimental confirmations were celebrated as great scientific achievements. The latter made the physicists obviously blind to the contradictions of the foundations of the theory of relativity and led to an immunization against critical statements on the theory of relativity. Explain this in simpler terms.arrow_forwardFor a hydrogen S level which of the following relativistic corrections is absent? Select an answer and submit.

Discuss what is meant by the term “highly relativistic.” (Note that, in part, it means that the particle cannot be massless.)
